Pokemon event
the galactic key is in the veilstone city ware house
You have to get the 7th gym badge and then you go to veilstone city, then go to the big ware house talk to the galactic grunt outside the big ware house talk to him and then pick up the item he drops then go to the tiny ware house with your new key you can open the door inside. Then get the key in the tiny ware house then with your new key you can open the door in the bigger ware house, get to the top of it battle the boss then get to the trapped Pokemon free them then get to the top of mt coronet then beat the commanders then talk to PALKIA battle PALKIA till he has one HP then catch him.
In Pokemon Platinum you dont get the key from a grunt you get from the detective, before getting the key you have to go talk to prof. rowan in the library .
if you mean the ware house there is a grunt you battle in front of the main building if youwinj they leave a key to the ware house in there youll evntualy find a key to the main building(make sure your Pokemon are fully healed because in both buildings theres loads of battles)hope that helped
